Creating an Initial Spark Table for Tuning

This is a tool for establishing a baseline spark advance table for your tuning efforts with MegaSquirt® or MicroSquirt® controllers. It is designed to work in Mozilla Firefox 6.0, though it may work with other browsers. It is based on the 'rules of thumb' presented here: Making a Spark Advance Table

This calculator has not been tested on all possible engine combinations and operating parameters.Use it at your own risk.

1. Input:

Fill in all of the values below (use your best estimate if you don't have measured numbers, but remember your table will only be as good as your estimates, and sometimes quite a bit worse).

2. Generate the Advance Table in .TABLE format:

Click on the "Generate Advance Table" button:

A 'pop-up' window will open containing the .table formatted text (you may have to disable any "pop-up stopping" software). If you get an error alert instead, you will have to correct your input values before continuing.

Open NOTEPAD.exe (under Start/Programs/Accessories/Notepad)
note- WordPad does not work, you need a text editor that preserves the spaces but not the html tags.

'Paste' contents into into Notepad (Ctrl & V),

'Save' as 'YourFile.table'.

3. Verify and Load to your MicroSquirt:

Open TunerStudio and navigate to 'Basic tables→Spark Advance Table' then click on the down-pointing greed arrow icon, and browse to select YourFile.table',

Burn the values to the controller if prompted,

Verify that the spark advance numbers and map/rpm bins are suitable for your engine.

Remember that the table generated is only a starting point for tuning. Using the generated table as a 'final' table under severe operating conditions can destroy your engine. Be sure to follow the tuning guide, and get professional assistance whenever your are not sure.
